"It has all the correct ends, seat belt clips and points. The spec says R53, 54 mini however we are confident that it also fits the R55 mini. But NOT the Mini Countryman
It must be the Cooper and Cooper S."

shipping looks to be around $60 with a quick look. i have the harness listed for sale here for $300. ill do $350 shipped for you, and if paypal, cover the 3%, so $361 total. i paid more for that shipped locally to me, so i am eating around $100.
let me know. thanks!
